Content preview from Java Pocket Guide

Preface

Designed to be your companion in the office, in the lab, or even on the road, this pocket guide provides a quick reference to the standard features of the Java™ programming language and its platform.

This pocket guide provides you with the information you will need while developing or debugging your Java programs, including helpful programming examples, tables, figures, and lists.

It also contains supplemental information about things such as the new Java Scripting API, third-party tools, and the basics of the Unified Modeling Language (UML).

Coverage is provided through the Java 6 Platform.

Book Structure

This book is broken into two sections: language and platform. Chapters Chapter 1 through Chapter 8 detail the Java programming language as derived from the Java Language Specification (JLS). Chapters Chapter 9 through Chapter 18 detail Java platform components and related topics.
